1. The document describes the author's experience using their senses to examine an unknown object in an aerosol can without seeing it. They feel the rough and smooth surfaces, concave bottom, and lid on top. 2. Upon shaking the can, the author hears no sounds, indicating it is empty. Putting their fingers in the holes on the top, they cannot determine the purpose. 3. After the time is up and they can see, the author discovers it is a medical aerosol can for wart removal, with an applicator holder in the top holes. They learned not to make assumptions without fully examining the object.

2. I was given a brown paper envelope, policy envelope in a size of 4’’x9’’, from
my partner. It contains an unspecified tool that was assigned by the lecturer to
be discovered. As requested, I hold the envelope under my desk and reach
my hand into it, took out the tool, and unhand the envelope to the floor. It is
very light object. Based on my random access memory, I know that I’m
holding anaerosol can at the moment that my fingerprint land on it. ‘’It is
easy’’, I laughed to myself as I thought it must be a spray bottle. I am relief at
the moment; because I was worried that my partner would bring some
unfamiliar object that I might have a tough time to dealing with.
Unfortunately, there arestill some lingering doubts in my mind. I must handle
that tool with caution for it might be a nightmare when it turns out to be a
spray can paint without its lid. I am certain that I won’t appreciate for the joke
from my partner after noticing myself in whatever colors it has. I started with
the investigation through touch using my both hand. It has two surfaces on it:
rough top and smooth bottom. I can hold it with one hand and I found that it
has a concave bottom. As I sense toward the top of the can I notice there is a
non-metal lid on it. I’m grateful that it covered with that rough surface lid.
Although it has a lid I was stunned afterward, as I learned that no matter how
hard I attempt to force itto rotate or lift, the lid cannot be open or loose. On
that account, it must not be a spray paint and I decided to sense the top using
my index finger to find if there is detail I’ve missed. Surprisingly, it has a lot of
holes on the top. There are some small holes in circle and rectangular forming
a circle surrounding a big circular hole. I doubt it and then put my index finger
into that hole, but I cannot reach in, so I put my pinky finger in yet I cannot find
what is it made for. After the same attempt for a few times, I went distress as
there nothing else for me to discover.

3. I’m drowned into serious concern that it is all I can find from the aerosol
can. After spending some moment to think is there other detail yet to be
uncovered. I started to shake the aerosol can, as I know if it is empty or filled.
Despite that I have shake it very hard there are neither sound nor collision
coming from inside, which indicate that the can is empty and no metal ball. If
my memory set me right, most of the aerosol can would have a small metal
ball inside which act as a disturbance to soften the particle inside. Soon I
notice that there’s no change in thermal index. Therefore, I make a hypothesis
that it must be an empty aerosol can. Most of the aerosol can undergo
enthalpy change as the particles inside the fixed volume were put under
pressure by shaking it, which a change of temperature would be noticeable.
Then I found the can are odorless as there’s nothing I can do about it, but I
won’t taste the aerosol can as I refuse to risk my health for this project.
Finally, the fifteen-minute examination time was over. I open my eyes in
a flash and I saw a pure white aerosol can with a ‘WARTNER’ print return on
it. I found a expiry date printed on the bottom of the can. Later on, I saw a line
wart & verruca remover, which smashes all my doubt away. It is an aerosol
can function for medical aid. Besides, the top of the can must be enclosed as
it can freeze anybody who is in attempt to open it up just like what I did in the
previous discovery. Also, I learn what is it in the big hole on top of the can for.
It was designed to insert the applicator holder to freeze a foam applicator. My
partner told me that it is filled so I return it to him.
In the end of this discovery session, I realized that there are things that cannot
be judge by your mere assumption, which might lead you to jump into
conclusion. It will confuse your judgment and making the wrong
decision.Sometime it is not what you think it is.
